arcgis.learn python api IndexError: index 0 is out of bounds for axis 0 with size 0

Question

Hello,

I'm trying to retrain Arcgis's Door and Window model with the ArcGIS Python API, but I'm getting an error. I am new to the field of deep learning. I will share the full code and error below. I tried a lot but I couldn't find how to fix the error. Thank you.

This is the error I got.

I am also sharing the full code.
